Application filed October 21, 1912. Serial No. 726.860.

To all whom it may concern.'

Be it known that. I, Hanvnr of Bonndbrook, in the county'of Somerset and State of AYew Jersey, have invented certain new and useful Improvements in Asphalt Roofing. whereof the following is a specification, reference being had tothe accompanying drawings.

My invention has for its object to provide asphalt rooting sheets with a surface capable of vreceiving and retaining a smooth coat of paint.

Ditiieulty has long been experienced in the etlort to paint asphalt and other bituminous rootinfxs because of the fact that rooting felt when saturated with or coated with abituminous cement presents a surface which is uneven and one to which paint does not adhere, so that the painted surface is neither smooth nor permanent. but tends to peel or "blister off. Many efforts have been made to solve this problem. l have discovered a solution which is dependent upon the interposition between the rooting! sheet and the paint of a comparatively thin' sheet of ordinary paper. The presence of this sheet of ordinary paper upon the surface of the roofing felt does not interfere with its desired qualities as a roofing material. while at the same time it affords a smooth surface which readily takes and retains paint.

ln the accompanying drawings7 I have illustrated a simple form of roofing-embodying my invention, in which- Figure l, is an enlarged perspective view with the, layers successively eut away and Fig. ll. is a sectional yiew. ln these drawings the thickness of the paper and paint layers are necessarily exaggcrated I have illustrated the roofing proper as composed of a single sheet of rooting,r felt 1. but it is obvious that various other compound sheets may with similar advantage be used in connection with my invention. The. main rootingr sheet l. consists of roofing felt which has been saturated by asphalt fluxed with oil. llpon'the side of this roofing sheet there is applied a sheet of moderately thin ordinary papel' il. This sheet prior to its application is similarly saturated with a compound consisting of asphalt and oil for example Trinidad asphalt and Specification of Letters Patent.

Trinidad asphaltic oil. The two sheets thus saturated are united by a heavier asphaltic' cementinp.r medium which adheres tenaciously to the rooting sheet and also to the saturated paper. entering the pores thereof. and loecoming more or less incorporated tl'ierewith, but not passingr completely through it, or modifying; the paint-receiving capacity of the outer surface ofthe paper. Upon the outer surface of this papel' sheet a layer of ordinary paint 3, may be applied.` The paint enters into the interstices of the paper be. coming1r more or less incorporated therewith', and the incorporated particles of the paint eommingle with those of the asphaltic cepaint and. the rooting sheet in order that the. inseparably combined, thiis*I overcoming,r the diiiiculties which aste-'X- occur when the paint is applied di two may he plained rectl y to the roofigg sheet. i

The paper 'should be thin enough not to add materially to'the thickness of the roofing sheet. of.a fine enough texture to present a smooth surface. It should be sufficiently absorbent to permit of partial incorporation with its substance of the asphaltic cement applied upon the one side. and the paint upon the other. and on the `other hand it should not be so open or porous as 1s atextile fabric. Such a' textile fabric absorbs so much asphaltic cement as to allow the asphaltic. cement to completely penetrate it. thereby defeating the. object which the present invention has in View, for the asphaltic cement which has penetrated a textile fabric affords no better surface for -the application of paint than the surface of the roofing sheet and for the same reason.
